If you live in an area that freezes, you really need to bring the birdbath inside for the winter. No matter what you do, the tiles can pop off as the piece expands and contracts in the cold. That being said, I did a birdbath last spring and it is holding up great. I did mine on a terra cotta saucer, but the process should still be the same. I started with a 14" terra cotta saucer like the ones that go underneath clay pots. I rinsed it out and made sure it was free of debris. After it dried, I applied three coats of a penetrating sealer for tile and grout. The one I am using has a 5-year warranty and is a matte finish. There are many products on the market that have a 20-year warranty but they are much more expensive and since I am new to this, I didn't want to go to the extra expense right now. A couple of days after I applied the sealer I adhered the tiles with a pre-mixed concrete patch. Since I was working in the house I didn't want to try and mix my own mortar or thinset. I used the indirect method by designing it on contact paper first then laying it in the bottom of the saucer after I put a thin layer of the concrete patch on the bottom. I used vitreous glass tiles with some light blue glass nuggets in the center. I kept the design very simple as I was not in the mood to cut a bunch of tiles. After three days of letting the adhesive dry, I grouted it with a gray sanded grout using Admix as the liquid. I sealed it with the same matte finish penetrating sealer after the grout cured for several days. I think the most important thing is that the adhesive and the grout have sufficient time to set before use. Good luck with your project. Here is a link that might be useful:

H B I think that is not “art” but the operational controls for the toilet ******************************* Yes, I think it's one of those toilets that washes--and dries you

I've never considered them to be bird baths when they are on the ground but I know the things you mean. I have seen pictures of some lovely ones in the shape of shells that are similar to yours but they don't have the beautiful figure watching her reflection as yours does. Actually, I think they were described as small reflecting pools. My parents used to have one that was made of mud coloured resin and it had a 3D image of a woman's face in it so that when it was filled with water the tip of her nose was just below the surface. The critters could drink from it but not bathe in it and make it dirty. I loved that thing. Darn, now I have to go look for one on e-bay!

I mean, they LOOK like sempervivum! LOL But I have no way of knowing whether they're some sort of hybrid or something. Last year I filled it up with what were labeled as Blacks, Royal Rubies, Cobweb Buttons, and then added a Blue Heron echeveria, Ice Plant, and Lemon Ball. I moved those last three to the greenhouse and left the first 3 in the pot, but they all died. For drainage, I drilled about 20 holes through the cement (I think the bit is 3/8", but it could be 1/4"), and the soil is a mix of potting soil and perlite (I think I did 60% soil 40% perlite, but I can't swear to that). Everything seemed great through the warm months so I don't think that drainage is an issue? I didn't buy new sempervivum this year, I just put the Lemon Ball and Ice Plant back in. They all did well, but it's getting close to time for me to put them in the greenhouse.
